IMPROVEMENT IN HAND SPINNING-MACHINES.

Specification forming part of Letters Patent No. 50,094, dated September 26, 1865.

To all whom t may concern:

Be it known that I, J EssE BYEKrr,of Fairfield, in the county of Jefferson and State of Iowa, have invented a new and useful Improvement in Hand Spinning-Machines; and I do hereby declare that the i'ollowingis a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a plan view of a hand spinningmachine which embraces my invention. Fig. 2 is a side elevation thereof. Fig. 3 is an end view.

Similar letters of reference indicate like parts. A

This invention has for its object the improvementofhand spinning-machines in which the spindle is mounted on a carriage that travels to and fro on the frame.

It consists, among other things, in shortening the bench, changing the position of a portion of the gearing, placing the treadle so that it is operated from the end of the frame instead of from the side, forming a box to receive vthe carriage, &c.

A designates the bench of a railway hand spinning-machine,havingan open bottom, and properly supported at a suitable height above the ground or iioor.

G is the traveling carriage that carries the spindle. This carriage is provided with metallic wheels, which run on a track formed on ways on the top ofthe bench. The spindleis driven by a band, f, from the wheel e, whose shaft has a smaller pulley, which is driven by the band b, the said band being made to go entirely around the said smaller pulley.

C is a frame built up at the end ofthe bench for the purpose of supporting the treadle D and the driving-gear wheels B B.

The ordinary hand spinningmachines of this kind have their main driving pulleys or wheels placed within the ends of the bench and the drivin g-band running directly from its periphery to the operative parts of the machine, thereby occupying space which is needed for the movements of the carriage, and consequently shortening its traverse, or else re- Y quiring the bench to be made longer by thev amount of space taken by the wheels. They have also the treadle in such a position as to be within reach of the spinner, whois required to sit at the right-hand side, (observing Fig. 3,) with one hand back to the crank and the other forward to the spindle,which,as above stated, can run no farther back than the pulleys. In consequence of this construction the present machines are required to be about ten feet in length.

1n constructing machines ot' this class according to my invention, I make the bench about two feet shorter, and form at the end where the power is applied a frame, C, which sustains the driving pulleys` and also the treadle, enabling me, among other things, to set the treadle in the direction of the length of the machine on the left-hand side. The treadle is provided with a foot-board, which is reached with the foot from behind the frame, the end of the treadle being connected to the pulley F by means of a cord in the usual manner.

Spinning-machines of this class as heretofore made have the wheel at the side where the spinner works; but I provide double pulleys B B on the right-hand side ofthe bench, the latter one being placed low in the frame and beneath the track of the carriage, and heilig driven from the upper one, B, by a band, d.

The power to drive the machine is applied to the shaft of the upper pulley, B, by means ot' a crank or other suitable device. The carriage G is moved in and out bymeans of the band c, whose ends are attached to the ends of the carriage, the band being taken over sheaves h at opposite ends of thc bench and around the pulley F. vWhen the pulley F is rotated by the motion of the treadle the carriage is caused to move on the bench. The rotation of the pulley e, which drives the spindle, is effected by meansof the band b, which is passed around the smaller pulley g on the shaft of pulley c, and thence over sheaves h at opposite ends ot' the bench, and around the driving-pulley B. At the outer end of the bench l make a bor, H, within which the carriage and spindle are received at the limit of their outward traverse, and within which they are protected from injury by accident and from handling when the machine is at rest.

By means of my invention the spinner is enabled to sit in a straightforward position at me to shorten the bench and to run the carriage to the driving end.

2. In hand spinning-machines, so placing the driving or crank wheel and the treadle, for running the carriage in and out, that the spinner can sit behind the end of the machine while at Work, substantially as described.

3. In hand spinningniachines, providing a box at the outer end of the bench to receive the carriage, substantially as described.
